What makes our fineOne a real highlight is the flexible nylon brush nib. You may create any line widths between 0.5 to 5 mm. And should you be afraid that the nib might be tender or sensible – don’t worry! Whatever pressure you put on the nib it will straighten up again. When it comes to visual sketchnoting or notetaking the fineOne ArtMarker belongs to one of our favourite markers. It colours any outlined surfaces quickly and swiftly.

The environmentally-friendly fineOne is a refillable marker with its easy to use water-based ink refill technology which can refill your fineOne up to 45 times!

the nib is just great

I have bought the 101 grey one to do shadings during sketchnoting. And the Nib is just really elastic, the description says 0.5 to 5mm, I would rather say just below 1mm but up to nearly 1cm. Also this grey is still relatively light and on can, by passing several times over the same spot, add colour and get some really quite nice gradients.
also, drawing directly over a line with the normal fineOne-black does not smudge at all.
Good buy

Wonderful colour, fantastic nib

I was somehow reluctant when I ordered this marker. Now I'm happy that I bought it!
I use it to shadow my sketches: the combination of light grey colour and brush nib gives life to my boring stickman sketches and my simple banners. Very good purchase!
